Area Forecast Discussion National Weather Service Austin/San Antonio TX 241 PM CDT Mon Jul 6 2020

SHORT TERM (Tonight through Tuesday Night). A weak low across North Texas and a weak boundary extending from this low southwestward through the Hill Country and toward Del Rio has helped to generate an MCV type feature with a line of showers across the Hill Country and isolated light showers both out ahead of and behind this small line. SPC has thrown in a marginal risk for severe storms across Central Texas as there will be enough instability, moisture, and lift in place to perhaps generate some strong storms later this afternoon. Otherwise, it is hot across South Central Texas, with most locations in the low to mid 90s as of 2 PM (already 101 at Del Rio and may break another record today). Dew points around 70 along the I-35 corridor to mid 70s across the Coastal Plains have heat index values ranging from 100 to 106 at the moment, with heat indices maxing out in the 103 to 108 range by mid to late afternoon.

The weak low will remain in place tonight NNE of the region as well as the remnants of the boundary/shear axis, and an additional surge of enhanced moisture late this evening will lead to the chance for additional development of showers and thunderstorms through the overnight and early Tuesday morning period, especially for Central Texas. Some decent rainfall totals (on the order of an inch of so) could be possible up across portions of Burnet and Williamson Counties.

Isolated showers and thunderstorms will continue through the day on Tuesday as the weak low will linger across NE Texas and moisture levels will remain elevated. High temperatures for tomorrow have come down a degree or two from previous forecast packages, but high temperatures will still range from the mid to upper 90s with enhanced dew points making it another uncomfortable afternoon. Warm and humid conditions are expected again for Tuesday night into Wednesday morning. Some of the convection allowing models as well as the GFS indicate that we may see an MCS of some sort late Tuesday night NW to W of San Antonio, but confidence in this is not particularly high at this time (only 20 PoPs during this period

LONG TERM (Wednesday through Monday). The long term remains hot and dry. Upper ridging to our west will dominate through the forecast period. High temperatures will likely be greater than 100 for almost all areas starting Friday. Over the weekend, the heat index will creep into heat advisory criteria with Sunday being the warmest day. As we start the new week, no real changes come into play with a hot and dry forecast.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
